So, let’s build it! brew tap homebrew/dupes The grep built with OSX is not 100% exactly the same. Note* 8/29: Also, should you make a disk that is not the correct size, you can invoke the resize command to fix it! hdiutil resize -size G ~/Desktop/.dmgĬrosstools relies on the use of GNU grep. The file system needs to be case sensitive. So create a non-case sensitive image and format it to a case sensitive one. Note 8/29: for some reason there is a bug on OSX which prevents you from formating a case sensitive drive in Disk Utility. (When fully compiled and compressed everything turned out to be around 107MB) The next disk can be exactly the same but only 250MB in size. This will house all the source code and object files when all said and done. I believe by the end of this process that this was not necessary for getting crosstool-ng to work.
Note: this is more of a precaution then a requirement. Be prepared to wait a little while everything assembles. Note: a few other dependencies get installed when crosstool-ng is compiled. If you haven’t already installed it you can run the command below: ruby -e "$(curl -fsSL )" You will need Hombrew to install some dependencies. It will save you a whole bunch of time to download it here rather than go through this procedure.įor those who want to continue for giggles, by all means… Install Homebrew Before we get startedīefore we start anything I recently compiled the toolchain for RPi3. So without further ado lets do this thing. Steps can be tweaked to account for older Pis
Note 8/29: This tutorial now is focused on the Raspberry Pi 3 B. I’m currently running a Macbook Pro with 10.11.6.
Update 8/29/16: I have updated this tutorial in several places for newer systems. Luckily, with this post you can get yours working in no time. If you are unfamiliar with the process of compiling a toolchain on your own computer, let me be frank: it’s not fun. It enagbles anyone to create a toolchain to compile Raspberry Pi code directly on a (much faster) Macbook. AĪfter I did some brief research, I came across crosstool-ng. In my previous posts, I came to the realization that the Raspberry Pi is not very fast! This results lots of chair spinning time while waiting for my projects to compile.
